After five weeks of maintenance on the Affordable Care Act’s glitch-ridden website, Americans should have an easier time logging on since its launch Oct. 1, officials say.

The website’s registration functions were up and running Saturday, a departure from the crash error messages many users experienced since its launch last month. White House officials say it can now handle up to 50,000 users at once, accommodating up to 90% of users, Reuters reports. However, no numbers were provided on how many users could actually complete the enrollment, and during peak hours some users may be directed to return to the site at a later hour.

“With the scheduled upgrades last night and tonight, we’re on track to meet our stated goal for the site to work for the vast majority of users,” said Aaron Albright, Centers for Medicare and Medicaid Services spokesman in a statement to Fox News.

With a Dec. 23 deadline, officials hope to enroll around 7 million uninsured and under-insured people in 2014. The botched rollout of President Obama’s healthcare marketplace was mired in function errors, causing the delay of insuring thousands of Americans.
